I have 2 minis both with rear window demisters that don't work but everything else does so its not likely to be a fuse.

Any suggestions

in the same boat mate, the light on the console comes on when i press it to heat the windscreen but no joy i dont think!

[Jammy]

I think the connections at the side of the rear windscreen usually get disconnected.

No, all connected, telltail lights work just nothing at rear screen.

do you have voltage at the screen ?

[MINImayfair1988]

same here if ne one got a solution it welome here lol i just use a shami lol

[Cookie Monster]

Must admit, haven't checked voltage yet, just though someone may have had same prob and a quick fix.

Sounds like I am not the only one though

holly i can check yours if you are this way or i will look next time we are at a cmc meet

[MINImayfair1988]

if you have power at the screen try cleaning the screen with white spirit, wipe it over then leave it to dry, ive done this before and worked fine after, just a thought

You really got to put a volt meter on it, or a bulb connected to the connections..
switch on, if it does not light (check the bulb on the battery) then you got no power coming in..

meter is about 4 quid for a digital one from maplins..

A must for a mini owner.

If it is not that i.e. you have voltage....
then the element could have a break in it..
again a volt meter on continuity on the terminals should give you a reading (less than 1)..
no reading and you have a break in the connection somewhere..

you can push the meter lead pin into the element (thick part) and track down the break..

once you find it you can get a heater element repair solition from Maplin (about 5 quid) you just paint this stuff over the break ..

sounds long winded but it is actually pretty simple..

hope this helps..

yeah that paint stuff doe swork becus ive had the same prob n went 2 auto window screens and that was the advise they gave me.

[Cookie Monster]

Cheers, have got a meter but a bit to wet to check ATM

[Cookie Monster]

Right, have power at screen

Have a good earth

Have continuity (less than 1) from side to side

Still not working.

Will get soeme repair liquid and paint it on next but so far no indication as to why not working.

next remove just one plug on the heater and see if theres any voltage petween the lose plug and the screen heater :erm:
